I'll keep my intro statement short, since this review is meant to praise Renanim and their amazing beds as well as their superb customer service. (I'm writing this review because I want to, and haven't been promised anything in return for what I say in this review) My boyfriend and I had been discussing purchasing a new mattress for the looongest time since our previous king size mattress and box spring was causing us to wake up feeling like our backs were broken, lol. Initially, we were going to get just another "regular-shmegular" mattress until we started talking about adjustable beds. This is where I tell you why this company is the ONLY company to even consider if you're looking for a QUALITY adjustable bed. ✔️Affordability - (without having to sacrifice quality). We did hours and hours of research online and saw SO many overpriced adjustable beds that only offered the base without the mattress. We wanted a split king so that we could adjust our sides independently, therefore by the time that we would've bought the bases and 2 twin XL mattresses, we were looking at over TWICE the amount that Renanim was asking. Which to me, is ridiculous. Oh, and might I add that we did our research during all of the 4th of July sales, meaning that the crazy high prices were on sale and were still sky high! With Renanim, we received both Twin XL adjustable bases as well as 2 Twin XL split king mattresses with cooling gel memory foam all together in a bundle deal for a fraction of the cost of the other leading adjustable bed manufacturers! This brand has the BEST prices out there hands down! ✔️ Setup was easy! Our bedroom is upstairs, so obviously we had a bit more lifting and carrying to do, and the bases are quality made causing them to be pretty heavy. Its definitely doable with 2 people, though, and once we got everything upstairs - it was a breeze to set up. Now that I've touched on price, I'll explain how this bed has literally changed our lives... ✔️ A good night sleep is essential to your everyday life and quality of life. Waking up with back pain caused from your bed sucks. Choosing a bed that gives you the option to adjust your head and legs, while also providing a "zero gravity" setting has completely changed the way that we sleep. We look forward to hanging out in bed watching our favorite shows and no longer wake up with back pain. The mattresses are very comfortable, and just the right firmness. We couldn't be more grateful for our new bed. ✔️ There were a few "extra" things that caught our attention that we thought were really cool like, the under bed light, the USB charging ports built into the frame on both sides, the MASSAGE setting, the flashlight built into the remotes, and the extra storage space under the bed. All of those things have proven to be awesome, and we use them interchangeably all of the time. ✔️ Finally, I have to tell everyone about the amazing customer service that we received. Prior to purchasing, we took measurements of our bulky, solid wood existing bed frame to make sure that the adjustable bed would fit inside and it absolutely did. However, we needed to add some height to the adjustable legs so that the mattresses were taller than our existing bed frame. We contacted customer service and explained the issue, and without hesitation, they sent us the extra add on pieces for the legs free of charge and shipped them immediately. Customer service put our satisfaction first, and really went above and beyond to make sure that we were 100% happy with our bed. Thank YOU Renanim! It was a pleasure purchasing from you, and we are loving our new bed! I will continue to pay it forward by telling everyone about your wonderful company, and hopefully help change a few lives along the way! ❤️

Great frame so far. Had them a little over a month. Very easy set up. But they are heavy so make sure you have two people there to flip them after installing the legs. They are very smooth on adjusting. Not as loud as I thought they would be. Which is a good thing.

My husband and I bought this system when I was pregnant and expecting. I had a high risk pregnancy, and the though of having to get up out of bed with a csection incision did not sound amazing. We were due for a new bed, and we decided to splurge. It did not disappoint! The mattress we chose was medium and while my husband enjoys it, I would have opted for something a little more firm but dont let that stop you. Be sure to choose the mattress that's right for you! The bed has a massage feature that my husband enjoys after a 16 hour shift outside, and the bed raises quite high. The beds are split so my only qualms with it was the void between the crack of our beds where things disappeared but that's easily fixed by getting a pillow to insert in the crack. The up and down functions have made postpartum recovery so easy after a csection, and having this bed in general makes comfort easily achievable.

It's been 2 days since we got our split king adjustable bed and all I can say is.... Hallelujah!!!!! I woke up 2 days in a row without back pain, or exhausted due to inadequate sleep. I read almost all the reviews and I have to say they helped tremendously with my decision to buy this bed. It was a BREEZE to set up as well. Everything worked correctly and no missing parts. It was 30 minutes from time of unboxing to having the entire 2 pieces of the split king put together and me & my husband lying in it playing with adjustments. It did take about 12 hours for the mattresses to completely expand though. And that's NOT a complaint. The motors are so quiet that I didn't even hear my other half raising and lowering his sections of the bed while I was lying next to him. It took 2 days to show up at my door after ordering, a full 2 days prior to schedule. That's another big plus. The bases are quite heavy, but considering the whole thing is already put together FOR YOU, it's worth it. Highly recommend this bed. I'll make an amendment to this post in a few weeks.

Buyer must pay to return during return timeframe! This bed has caused more back pain, discomfort and aches. I am on bedrest and thought this bed would help alleviate but instead has caused more aches and pain. Massaging function does not work well - bed mattress medium to firm is not medium nor close to firm. I am 130 pounds and despite changing from one split twin to the other regularly these beds have started to have sink holes and it has been less than a month of use due to mattress arriving later than adjustable frame. Extremely disappointing that returning would cost to send back a product that was misleading on returns policy. Buyers beware - I ordered from Amazon to ensure returns were possible; if had the opportunity to do again I would order from local store with easier return.
